BEARING FOR SPINNING-FRAME SPINDLES.

SPECIFICATION forming part of. Letters Patent No. 284,775, dated September k11, 1883.

/ Application filed January l0, 1'883. (No model.)

To @ZZ whom t may concern:

Be it known that we, GUsrAvUs E. TAFT and HENRY FgWooDMANoY, citizens of the United States, residing at Whitinsville, in the county of lVorcestcr and State of Massachuseti's, have inventedcertain new and useful Improvements in Bearings for Spinning-Frame 13Spindles, of which the following is a specificaion. A

Our invention relates to bearings for spinning-frame spindles; and the objects of our improvement are to provide a simple and effective bearing for spindles,whereby brous or springy packing to retain the spindle in proper position is dispensed with, and the noise ordinarily produced by revolving spindles is also prevented. We attain these objects by the construction illustrated inthe accompanying drawings, in which* Figure l is a vertical section, showing a spindle, its combined bolster and step, and bolstercase constructed according to our invention, the spindle being in elevation. Fig. 2 is a ver-, tical section through the bolster-case. Fig. 3 is a side view of the combined bolster and step.

Heretofore many attempts have been made to prevent the jarring, wabbling, or uneasy motion of running spindles, caused by any inequality of bobbin or yarn load on the spindle, and thus reduce the wear of the bearings, the most com/mon method being by means of elastic packing or springs placed around the bolster; but their properties seldom last for any length of time. By our construction the means to give elasticity and freedom of adjustment to the bolster and step are not subjected to any wear or deterioration.

. In the accompanying drawings, A represents the spindle, to which is secured, as usual, the sleeve or cap a, carrying the whirl a', by which motion is transmitted to the spindle. The spindle is supported sidewise by the bolster B and endwise by the step B2. These parts B and B2 are preferably made of bronze, and are driven tightly into the tube B, producing with the latter a substantially rigid combined bolster and step, having a chamber, b, between the lower end of the bolster and the top of the step for the reception of oil, mainly, to lubricate the interior of the bolster. There is also a chamber, b', in the lower end of the tube B, under the step B2, to receive a short cylindrical stem or pin, c, projecting upward from the bottom of the bolster-case C, and also retain some air to act as a cushion between the top of said stem c and the bottom of the step, to

prevent any vertical thumping of the lower end of the tube B against the bottom of the case C. The upper end, B3, of the tube B has pin, c', may be made to project in the interior of the upper portion of the bolster-case to enter one of a series of grooves, b2, in the upper portion of B3 of the bolster-tube or this ar- -rangement may preferably be reversed and the check-pin b3 be made to project from the upper end of the portion B3 to enter a shallow vertical groove, C2, within the interior of the upper portion, C. of the bolster-case, and this groove .C2 may even be in the form of a bayonet-holding groove. The interior of he bolster-case is chambered about the midd e of its length, at C, to hold a few months7 supply of oil, that finds its way through the holes b* under the bolster, and, by the lcentrifugal impulse given thereto by the spindle, penetrates between the bolster and spindle and lubricates the latter thoroughly. The upper end of the bolster is conical at b5 to yreturn within the case C anyV overflowing oil, the upper end of said case being a little higher than the eXtreme top b5 of the bolster. A

The tube B, as well as the interior step, B2, is perforated at b, to admit oil from the case C in close proximity to the point of the spindie. of tube B being only a little larger than the upward-projecting stem c in the bottom of the bolster-case, the oil contained within the latter becomes compressed under the oscillation of the spindle, rst in one direction, then in The internal diameter of the lower end IOO another, between the side of the stem c and the ster-case, producing a double liquid cushioning for the lower end of the combined bolster and step against the lower end walls of the bolster-ease, permitting the spindle to be sufiiciently deiected, so as to run true and uniformly7 even under inequality of bobbin or yarn load. A ring of cork or leather may be placed in the bottom of the cavity surrounding the central stem, c, as a cushion for the end of the tube B to rest upon.

rlhe bolster-case C is secured to the spinning-frame rail by anut, E, put on the threaded part thereof. It is cast in one piece, so that oil cannot leak out at the bottom, and when covered by the whirl no dust can get in at the top.

from its bottom, and entering` the chamber in" the bottom of the combined bolster and step7 substantially as and for the purpose described.
